This repository contains the Splipy packages. Splipy is a pure python library for the creation, evaluation and manipulation of B-spline and NURBS geometries. It supports n-variate splines of any dimension, but emphasis is made on the use of curves, surfaces and volumes. The library is designed primarily for analysis use, and therefore allows fine-grained control over many aspects which is not possible to achieve with conventional CAD tools.

The library is packaged on PyPI and can be installed through pip by simply running :

pip install splipy

• Getting-started guide - tutorial page (run with jupyter to get interactive features)
• Examples page - stand-alone executables of different applications
• API documentation - technical details on all functions
• Package installation page - splipy on PyPi, packaged and ready for installation

Splipy uses Poetry as a project management tool. To install poetry, use:

pip install poetry

Poetry is the only tool that must be installed outside of the virtual environment for Splipy. Once installed, run the command:

make install

in the root Splipy directory. This will install Splipy and its dependencies in a virtual environment located in the .venv directory.

You should activate this virtual environment whenever you work on Splipy. The makefile commands do not require it, but it's a good habit:

source .venv/bin/activate

To run the tests:

make test

To install, use:

pip install .

To generate a package (source distribution or wheel), use:

make sdist
make wheel
make build  # both sdist and wheel

Don't upload wheels to PyPI manually. They are built by CI runners whenever a new version is tagged (see below).

To generate the documentation, run:

make doc

To push generated docs online on the gh-pages branch, run the helper script:

python push_documentation.py [remote]

where remote is the name of the remote to push to. If not given, it will be asked.

To run the tests, use:

make test

For benchmarks:

make bench

To make a new release, run the bump-my-version command:

bump-my-version --dry-run <part>

Where <part> is the part you want to bump: either major, minor, patch, pre_label or pre_number.

You can also specify the new version directly by using:

bump-my-version --dry-run --new-version <new_version>

Once you are satisfied with the results, run the command without --dry-run. We highly recommend to always use a dry run!

After that, CI should automatically build and deploy the packages to PyPi. It would be helpful to monitor the actions so that errors can be fixed quickly.
